If you’re among the 65% who are trying to get swole this year, you’ll need to start working out — like, a lot. One good way to stay motivated is by investing in a fitness tracker. Not only will it help you get a visualization of everything you’re doing to stay fit, but it can also serve as some much-needed inspiration to get out of bed and hit the gym.

If you didn’t get a Fitbit for the holidays, now is your chance to save on something you actually wanted thanks to some great sales happening on Amazon.

The Fitbit Charge 2 is the gold standard for Fitbit wearables. Not only can it track your steps, calories burned, sleep cycle, daily active minutes, and heart rate with Fitbit’s PurePulse technology, but it can also deliver most of your smartphone’s notifications straight to your wrist with the Charge 2’s impressive OLED display. The fitness tracker is even splash-proof and comfortable enough to wear every day as your watch.

The Fitbit Ionic is a fitness tracker for more advanced workouts and hardcore gym-goers. While it can track all your steps, calories burned, sleep, daily active minutes, and heart rate, the Fitbit Ionic can also track your running and walking pace, distance, and routes in real-time with its built-in GPS. The Bluetooth-enabled tracker is water resistant for up to 30 feet, so it’s safe to use in the pool to track your swimming goals. In addition, it comes with a built-in “coach” to show you new workouts and help you get you through “the burn.”

The Fitbit Ionic can even store and play up to 300 songs with downloadable playlists from Pandora. If you need your fitness tracker to adjust to your workouts, then the Fitbit Ionic is for you.

If you’re looking to get in shape for 2019 and unsure what kind of fitness tracker you should buy, then the Fitbit Flex 2 is a super easy place to start. It’s Fitbit’s fitness tracker for beginners with an eye towards usability and comfort. Instead of having something big and bulky on your wrist, the Flex 2 is ultra-thin while it counts steps, distance, calories burned, and active minutes during your workouts and daily life. While it doesn’t have a display, it alerts you towards your workout goals with a series of vibration patterns and LED lights that are color coded. The Fitbit Flex 2 is simple to use and connects directly to your Android or iOS mobile device.

In addition, the tracker itself is removable, if you want to hide it in pendants and bangles for formal occasions (see below).

Fitbit offers an accessory bangle for the removable tracker from the Fitbit Flex 2. The tracker fits perfectly inside of this stylish bangle, which is made from 22k-plated rose gold and other premium materials and finishes. Just because you’re going formal for the night, it doesn’t mean you can’t track your steps and calories burned while out on the town.

Since the Ionic is a Bluetooth-enabled fitness tracker, Fitbit offers the Flyer wireless headphones as an accessory with automatic syncing with any FitBit device. With up to six hours of playback, the Fitbit Flyer delivers premium crisp audio and powerful bass for music and podcasts while you go for a run or work out.

If you don’t have a Fitbit Ionic, the Flyer wireless headphones work with just about any mobile device with Bluetooth 4.3 built-in.
